that s adjacent to it, and it can really happen at any time. but again, these airplanes are built for things like clear air turbulence. then you have mountain turbulence that we typically see in areas where there are mountainous terrain. that happens in san francisco as well, strong air that blows persoperpen dickdicular to the . the micro burst i ll completely eliminate from the situation. there were no thunderstorms in the area. we could have seen clear air turbulence or mountain turbulence, but those alone would not cause a plane crash like this, greta. yeah, janice. it looks like it was just a perfect day for flying, so the ntsb has its work cut out for them. the go team is on the way. they ve got people on the ground. they re doing investigations. they re going to seal the scene. they ll take the aircraft. just look at that aircraft. look at the top of that plane. it is absolutely stunning, and just as a viewer wrote me before, look what those flight attendants did. they evacuat
